The aim of the present study was to investigate (a) the neural correlates of a love induction task (LIT) including listening to love-related songs and thinking about the romantic relationship, and (b) the effects of romantic love on the emotional processing of love-unrelated stimuli during a passive viewing task. The EEG was recorded in two groups of university students: people in love (Love Group, LG, N = 22, 19 F) and people not in love (Control Group, CG, N = 20, 15 F). The LIT induced higher pleasantness and arousal in the LG than in the CG, as well as higher alpha activity in occipital-right electrodes, suggesting active mental imagery and internal focused attention. During the picture viewing task, the LG displayed larger N1 amplitudes than the CG in response to unpleasant pictures, and lower amplitudes of the late positive potential to both pleasant and unpleasant pictures at frontal sites. Overall, these results suggest an early attentional modulation of the neural responses to unpleasant, mood-incongruent cues, followed by an implicit emotional down-regulation of arousing stimuli, which might have important implications for everyday attitudes and behaviors.

本研究的目的是调查（a）爱情诱导任务（LIT）的神经相关性，包括听与爱情相关的歌曲和思考浪漫关系，以及（b）浪漫爱情对情感加工的影响被动观看任务中与爱情无关的刺激 脑电图记录在两组大学生中：恋爱中的人（Love Group，LG，N  = 22，19 F）和未恋爱中的人（Control Group，CG，N。 = 20，15 F）。LIT在LG中比CG引起更高的愉悦和唤醒，以及枕右电极的α活性更高，表明活跃的心理意象和内部集中注意力。在图片查看任务期间，LG响应于不愉快的图片而显示出比CG大的N1振幅，而较低的正电位幅度减小了正面位置的令人愉悦和不愉快的图片。总体而言，这些结果表明对不愉快的，与情绪无关的线索的神经反应的早期注意力调节，然后是引起刺激的内隐情绪下调，这可能对日常的态度和行为产生重要影响。
